Hi Abbie,

Thanks! My neurosurgeon said it is really rare to be affected by it as an
adult, and they/he have no clue why all of a sudden. It all happened while
I was spending a week at Lake Tahoe. I was staying at a resort that is
at 8500 ft altitude, I live at just above sea level. His guess is that maybe
the sustained altitude just pushed me brain over the edge.... who knows..

Glad your niece is doing well, she'll be just fine.

Thanks again for the welcome!
